Purpose: The aim of the paper was investigation of the effect of Cu addition on GFA (Glass Forming Ability), structure, magnetic and mechanical properties of amorphous Fe-Co-B-Si-Nb alloy. Design/methodology/approach: The following experimental techniques were used: differential thermal analysis (DTA), transmission electron microscopy (TEM) and X-ray diffraction (XRD) method, measurements of magnetic properties (VSM method), Vickers microhardness (HV). Findings: It was shown that when Cu is added to the Fe-Co-based alloy, increase of the GFA and change of the magnetic properties was obtained. Research limitations/implications: The results can give more details to understand the relationship between structure, magnetic and mechanical properties. Thus can be useful for practical application of these alloys. Practical implications: The (Fe36Co36B19Si5Nb4)100-xCux (x=0 and 0.6) metallic glasses due to their excellent soft magnetic properties have shown great industrial value for commercial application. Many products consisting of these kinds of metallic glasses have been widely used, for example anti-theft labels, precision sensor material, and high efficient magnetic transformers in electronic industry. Originality/value: The applied investigation methods are suitable to determine the changes of GFA and structure combined with magnetic and mechanical properties of (Fe36Co36B19Si5Nb4)100-xCux (x=0 and 0.6) metallic glasses

Purpose: The main aim of the paper was investigation of influence of copper addition on thermal, magnetic and mechanical (microhardness) properties of (Fe36Co36B19Si5Nb4)100-xCux (x=0 and 0.6) metallic glasses. Design/methodology/approach: The following experimental techniques were used: differential thermal analysis (DTA), transmission electron microscopy (TEM) and X-ray diffraction (XRD) method, measurements of magnetic properties, Vickers microhardness. Findings: It was shown that addition of small amount of copper to the base alloy induced a change of thermal, magnetic and mechanical properties. Research limitations/implications: The relationship between structure and magnetic and mechanical properties can be useful for practical application of these alloys. Practical implications: The (Fe36Co36B19Si5Nb4)100-xCux (x=0 and 0.6) metallic glasses due to a unique properties have been commercialized in the following application fields: precision mould material, precision imprint material, precision sensor material, precision machinery material and surface coating material. Originality/value: The originality of the paper are examinations of changes of thermal and mechanical properties combined with magnetic properties of the (Fe36Co36B19Si5Nb4)100-xCux (x=0 and 0.6) metallic glasses.
